1. Requirements

This package requires:

2. Installation

2.1. Install Composer package

First of all, install the Composer package from your CMD or your Terminal.

$ composer require mathermann/dohone-sdk

2.2. Implement TransactionInterface

Then you need a class that implements TransactionInterface interface.
For example:

<?php

namespace Your\Name\Space; // Replace with your namespace

use Mathermann\DohoneSDK\TransactionInterface;

class Transaction implements TransactionInterface
{
    /**
     * Transaction reference (or id) in your system
     */
    private $transactionRef;
    
    /**
     * Transaction operator, must be one of the following values:
     * ['DOHONE_MOMO', 'DOHONE_OM', 'DOHONE_EU', 'DOHONE_TRANSFER']
     */
    private $transactionOperator;
    
    private $transactionAmount;
    
    /**
     * Transaction currency, must be one of the following values:
     * ['XAF', 'EUR', 'USD']
     */
    private $transactionCurrency;
    
    private $transactionReason;
    
    /**
     * Transaction reference in Dohone's system
     */
    private $dohoneTransactionRef;
    
    private $customerName;
    
    private $customerPhoneNumber;
    
    private $customerEmail;
    
    private $customerCountry;
    
    private $customerCity;
    
    /**
     * Notification URL for this transaction
     */
    private $notifyUrl;
    
    // You can add some additional properties...
    
    
    public function getTransactionRef()
    {
        return $this->transactionRef;
    }

    public function getTransactionOperator()
    {
        return $this->transactionOperator;
    }

    public function getTransactionAmount()
    {
        return $this->transactionAmount;
    }

    public function getTransactionCurrency()
    {
        return $this->transactionCurrency;
    }

    public function getTransactionReason()
    {
        return $this->transactionReason;
    }

    public function getDohoneTransactionRef()
    {
        return $this->dohoneTransactionRef;
    }

    public function getCustomerName()
    {
        return $this->customerName;
    }

    public function getCustomerPhoneNumber()
    {
        return $this->customerPhoneNumber;
    }

    public function getCustomerEmail()
    {
        return $this->customerEmail;
    }

    public function getCustomerCountry()
    {
        return $this->customerCountry;
    }

    public function getCustomerCity()
    {
        return $this->customerCity;
    }

    public function getNotifyUrl()
    {
        return $this->notifyUrl;
    }
    
    // add setters...
    
    // you can add some additional methods...
}

3. Payin requests (collect payments)

3.1. Create a DohoneSDK object

You can find DohoneSDK class here.

<?php

use Mathermann\DohoneSDK\DohoneSDK;

// constants
define('MERCHANT_KEY', '...'); // your dohone merchant key (required)
define('APP_NAME', '...'); // the name by which your application is recognized at Dohone
define('HASH_CODE', '...'); // your dohone hash code (only if you handle dohone notifications in your system)
define('NOTIFY_URL', '...'); // default notification URL for incoming payments

$dohoneSdk = new DohoneSDK(MERCHANT_KEY, APP_NAME, HASH_CODE, NOTIFY_URL);

// ...

3.2. Make a « COTATION » command

<?php

// ...

use Mathermann\DohoneSDK\InvalidDohoneResponseException;

try 
{
    /**
     * $transaction is an object of type Transaction defined above,
     * $mode is exactly the same as "levelFeeds" in Dohone's documentation
     */
    $response = $dohoneSdk->quote($transaction, ['mode' => $mode]);
    
    if ($response->isSuccess())
    {
        echo $response->getMessage(); // display result
    }
    else
    {
        echo $response->getMessage(); // display error message
    }                
}
catch (InvalidDohoneResponseException $e)
{
    echo $e->getMessage(); // display error message
}

// ...

3.3. Make a « START » command

<?php

// ...

use Mathermann\DohoneSDK\InvalidDohoneResponseException;

try
{
    /**
     * $transaction is an object of type Transaction defined above,
     * $OTP is exactly the same as "rOTP" in Dohone's documentation, required only for Orange Money payment
     */
    $response = $dohoneSdk->start($transaction, ['OTP' => $OTP]);
    
    if ($response->isSuccess())
    {
        if ($response->hasREF()) {
            // ToDo: handle success
        }
        else if ($response->needCFRMSMS()) {
            // ToDo: request SMS confirmation code to user
        }
    }
    else
    {
        echo $response->getMessage(); // display error message
    }                
}
catch (InvalidDohoneResponseException $e)
{
    echo $e->getMessage(); // display error message
}

// ...

3.4. Make a « CRFMSMS » command

<?php

// ...

use Mathermann\DohoneSDK\InvalidDohoneResponseException;

try
{
    /**
     * $transaction is an object of type Transaction defined above,
     * $code is exactly the same as "rCS" in Dohone's documentation
     */
    $response = $dohoneSdk->confirmSMS($transaction, ['code' => $code]);
    
    if ($response->isSuccess())
    {
        if ($response->hasREF()) {
            // ToDo: handle success
        }
        else if ($response->needCFRMSMS()) {
            // ToDo: request SMS confirmation code to user
        }
    }
    else
    {
        echo $response->getMessage(); // display error message
    }                
}
catch (InvalidDohoneResponseException $e)
{
    echo $e->getMessage(); // display error message
}

// ...

3.5. Make a « VERIFY » command

<?php

// ...

use Mathermann\DohoneSDK\InvalidDohoneResponseException;

try
{
    /**
     * $transaction is an object of type Transaction defined above
     */
    $response = $dohoneSdk->verify($transaction);
    
    if ($response->isSuccess()) {
        // ToDo: handle OK
    }
    else {
        // ToDo: handle NO
    }                
} 
catch (InvalidDohoneResponseException $e)
{
    echo $e->getMessage(); // display error message
}

// ...

3.6. Handle Dohone's notifications

<?php

// ...

use Mathermann\DohoneSDK\InvalidDohoneResponseException;

// convert data into more readable format
/**
 * $notificationData is data received from the request, it can be
 * $_GET if you use vanilla PHP,
 * $request->query->all() if you use Symfony or
 * Input::all() if you use Laravel
 */
$data = $dohoneSdk->mapNotificationData($notificationData);

// check for request integrity
if ($dohoneSdk->checkHash($data))
{
    // fill new Transaction() with data and check if Dohone recognizes the transaction
    try
    {
        /**
         * $transaction is an object of type Transaction defined above
         */
        $response = $dohoneSdk->verify($transaction);
        
        if ($response->isSuccess()) {
            // ToDo: handle OK
        }
        else {
            // ToDo: handle NO (or just ignore the request)
        }                
    } 
    catch (InvalidDohoneResponseException $e)
    {
